💖 ARNO_FWFILTER 💖

okay bestie, welcome to arno-fwfilter, a filter script that makes your iptables firewall logs actually readable by humans 🌸 (yes, the man page name is ARNO_FWFILTER(1), that's the one, we're here, you made it)

✨ SYNOPSIS ✨

arno-fwfilter [OPTIONS]

🦋 DESCRIPTION 🦋

so arno-fwfilter is a pipe filter script, right? and its whole personality is making the firewall log better readable. that's it. that's the job. 💅

some usage examples, because the way that a demo hits different:

Static firewall log filtering:

arno-fwfilter < logfile

Realtime firewall logging on tty10:

tail --follow <logfile> | arno-fwfilter >/dev/tty10 &

like. look at that second one. piping live logs onto tty10 in the background? main character energy fr fr 👑

🎀 OPTIONS 🎀

  • --help, -h — prints all the available options for you, bestie 🫶
  • --no-resolve, -r — turns OFF resolving IPs to names. no name lookup, no problem ✨
  • --html-output, -o — uses basic HTML to format the output. she's a little web page now 💻
  • --no-locations, -l — turns off the (attempted) grabbing of the IP's geographical location. heads up: by default, http://www.hostip.info/ gets visited to get this info 🌍
  • --no-colors, -c — no colors in the output. monochrome moment, sad but valid 😭
  • --single-line, -s — puts all the info about an event on a single line. compact queen 👑
